Hello Everyone, **Application** : I have accumulation section with 24 beds and there's individual PE's for each section. I want to create a pop up window with all the PE's listed in table to show where exactly the jam is using the following script. step 1: I have multiple tags that I'm reading form a folder for an accumulation zone with 24 tags. so naturally built a tagpath list to read from. step 2: read all the tags and used list comprehension to generate another list to store values that i read. \*\*\*\ ***part I'm currently cant get past is step 3** step 3: tag\_value\_list is what I'm trying to attach to a data table. and where should I apply this script on. possibilities i have considered so far (button action performed, project scripts). ```auto acc_number = 12093701 bed_number = 24 end_acc_number = acc_number + bed_number x = [item for item in list(range(acc_number, end_acc_number))] print(x) #tag_base_path = "JAM_PHOTOEYES/12093730/1209370" tag_base_path = "JAM_PHOTOEYES/12093730/" tag_paths = [] # These two for loops iterate over a range and generate tag paths for us to read from for i in x: tag_path = tag_base_path + str(i)+"/AFE_Recirc_Pecblockage" tag_paths.append(tag_path) # this line reads all the tags at the path we specified tag_values = system.tag.readAll(tag_paths) #this list comprehension allows us to wrap all the values read in a list for us tag_value_list = [tag.value for tag in tag_values] # new to convert list into a dataset and bind data property of the table to this dataset tag print(tag_value_list) ``` ![code_snipped_pecblockupdate](https://us1.discourse-cdn.com/inductiveautomation/original/3X/f/a/faeaf3f756edfc1273c154b60472a9e3ee1614e4.png) ---

Please edit your post, highlight all of the code, then click the "preformatted text" button on the comment editor. This will make your code readable for us. ---

Thank you for your suggestion!! ---

So, you need to use the [system.dataset.toDataSet](https://docs.inductiveautomation.com/display/DOC81/system.dataset.toDataSet) function to convert from lists to a dataset. Note that it needs a **list of lists** , where the inner list represents the row. (Lots of examples scattered over the forum.) ---

so according to the manual parameters/arguments this function calls for is (header, rows). However, when I do so it gives me error showed in the pictures. `PecblockageDataset = system.dataset.toDataSet("value",tag_value_list)` ![image](https://us1.discourse-cdn.com/inductiveautomation/original/3X/0/7/0791edf133c85e2fc12d07d5c2248995fa3ec2ca.png) ---

In your code, `tag_value_list` is not a list of lists (yet). Consider something like this for `rows`: ```auto [[x] for x in tag_value_list] ``` ---

Thank you!. Now that I have a dataset to work with. can you guide me through the last process/question i had for this problem. where should i apply to script to? action performed on the button? and how can I link to data table in my pop window? ---

From a script, you would assign the dataset to a component's data property. Or to a property that fed a binding to the actual display property. Or provide the dataset to a popup window via parameters, using a dataset custom property in the popup's root container. (Or view parameter, in Perspective)
